FIELD OF THE INVENTION

The invention is about a new submachine gun that can be used as an assault weapon.

BACKGROUND

Today submachine guns are manufactured from various parts. The parts that are referred to as upper body, lower body, barrel, mechanism, etc., are developed for the users to be able to use the submachine guns more comfortably. The rounds that are generally used in submachine guns have calibers of 9×19 mm, 5, 7 mm, 4, 6×30 mm, and 6, 35 mm in the state of the art.

In the current art, there exists a system that holds a magazine, which keeps said rounds, stand firm when the submachine gun is being carried or used, and that prevents the magazine from being removed when not desired. However, there exists no system that allows a 9×19 mm magazine to be carried without adding an additional apparatus to the magazine slot.

In addition, in the current art, generally a barrel intermediary part is used between the mechanism and the barrel to mediate the pushing of the round from the magazine into the round chamber by the mechanism. This intermediary part causes problems by increasing costs as well as increasing the weight of the firearm.

The patent titled “full and hand-controlled semi-automatic submachine gun that fires 9 mm parabellum rounds, that has a mechanical stock of variable length, that locks itself, and that has varying lines of fire” with the application number TR 2004/03402 can be given as an example for the current state of the art.

According to the invention, the system automatically locks itself when the trigger is not squeezed due to the apparatus that is installed at the trigger system, and thus it becomes impossible for the firearm to fire a round unless the trigger is squeezed. When the trigger is squeezed, the angled piece that is part of the trigger system pushes the locking piece downwards and unlocks the trigger lock of the firearm. The cover set is locked from its front side and firing continues when the gunpowder gas reaches there and the lock is unlocked.

The invention that is referred to as an example is about the trigger system of submachine guns. However, the invention that is the subject matter of this application aims to implement improvements on the magazine, mechanism, and barrel parts of submachine guns.

The utility model titled “a bull pup submachine gun using 5, 7×28 mm rounds that is locked from the front, that can fire single rounds and is also automatic, that locks itself, that has two safety locks and an arm rest” with application no TR 2010/05257 can be given as another example of the current state of the art.

The application that is referred to as an example includes an additional part at the tail part of the barrel which allows for the locking of the firearm during firing. However, the invention that is the subject matter of the application does not have an additional part that connects the barrel and the mechanism. The barrel is directly locked onto the mechanism in the submachine gun that is the subject matter of the invention. Thus, submachine gun that is the subject matter of the invention is completely different from the invention that is referred to as an example.

In sum, the invention that is the subject matter of the application is about a submachine gun that uses 9×19 mm parabellum rounds and that can be used as an assault weapon, which overcomes the disadvantages of the current state of the art.

SUMMARY OF THE INVENTION

The invention that is the subject matter of this application is about a submachine gun that uses 9×19 mm parabellum rounds and that can be used as an assault weapon.

DETAILED DESCRIPTION OF THE INVENTION

The submachine gun consists of at least one upper body (1), at least one mechanism (2) that is included in the structure of the said upper body (1), a buffer (3) that is located at the rear end of the mechanism (2) in the upper body (1), a buffer coil spring (4) that is placed to circumvent the said buffer (3), at least one winding arm (5) on the mechanism (2) and at least one winding lug (6) that is integrated as a monoblock with the mechanism (2), a barrel (7) to which the mechanism (2) is directly connected to at the front part of the upper body (1), a lower body (8) to which the upper body (1) is connected to, a magazine (9) which is attached to the lower body (8), a magazine lock (10) that allows the magazine (9) to be removed and to remain locked when it is attached, a fixed ejector (11) that ejects the empty shell out of the submachine gun if the round is fired or the live round if the round is not fired, an ejection window (12) through which the live round or the empty shell is ejected, and a grip (13) that is located on the lower body (8).

In addition, the submachine gun that is the subject matter of the invention contains a barrel (7) round chamber a pin system to fire the capsule of the round that is in the round chamber, and a cock which has the function of hitting the pin.

In the preferred embodiment of the invention, the magazine (9) has the appropriate dimensions to hold round with a caliber of 9×19 mm and it has either a straight or a curved shape. The magazine (9) slot is characterized by its having the appropriate dimensions to directly accommodate straight or curved magazines (9) that hold rounds with a caliber of 9×19 mm without any additional apparatus.

The mechanism (2) that is the subject matter of the invention is a part of the submachine gun such that it allows for the pushing of the round in the magazine (9) into the round chamber (7), that it houses the pin system which fires the capsule of the round in the round chamber, that pulls the empty shell in the barrel round chamber (7) by its lug, that winds the cock, which has the function of hitting the pin, for a second shot as it moves backwards due to the recoil that arises from the firing of the round in the barrel.

The lug (6) on the mechanism (2) serves the purpose of winding the mechanism (2) with the help of the winding arm (5) and also preventing the rotation of the mechanism (2) around its own axis inside the upper body (1).

Unlike similar applications, the mechanism (2) does not have connecting parts that are attached to it later, but these parts are manufactured as a monoblock with the mechanism (2).

When the winding arm (5) is pulled backwards in the submachine gun, it connects to the winding lug (6) of the mechanism (2) to pull the mechanism (2) backwards together with itself and to squeeze the buffer coil spring (4). When the pulling force applied to the winding arm (5) is lifted, in other words, when the winding arm (5) is released, the mechanism (2) moves forward due to the squeezed coil spring (4) and pushes the round from the magazine (9) into the barrel round chamber (7) due to the structure of the slot.

Said straight or curved magazine (9) that can house 9×19 mm rounds has such a structure that its dimensions are suitable for the magazine (9) to be attached to the port without needing any additional apparatus and it can hold 9×19 mm rounds.

The front profile of the mechanism (2) is such that it would not scratch the walls of the magazine (9) and that it would fit into the barrel round chamber (7) as it pushes the round into the round chamber (7).

The mechanism (2) houses the pin and the pin housing which have different diameters by the different diameters set inside the mechanism (2).

There are channels (17) set on the lower surface of the mechanism (2) and thus forming its front profile. Said channels (17) prevent the mechanism (2) from scratching the neck portion of fixed ejector (11) and the walls of the magazine (9) as the mechanism (2) travels forward and backward along the axis of the barrel (7).

In addition to these, there are ejections placed along the side surfaces of the mechanism (2). Said ejections allow the mechanism (2) to operate without deviating from the barrel axis inside the upper body (1) that it operates in. Stated differently, they allow the operation along the barrel axis (7), thereby decreasing friction surfaces and heating caused by friction within the body of the firearm.

Ejection performed at the barrel allows the mechanism (2) to get into the barrel (7) and push the round directly into the barrel round housing (7) without the need for an additional part. This eliminates the need for an intermediary barrel (7) part. This ejection which also allows the round in the magazine (9) to be pushed into the round chamber with the help of the mechanism (2) also allows the mechanism (2) to lock onto the barrel (7). The radius on the surface of the barrel (7) where ejection is performed also serves as a ramp that helps the 9×19 mm round to be pushed from the magazine (9) into the round chamber. Since its form is the same across the diameter, it does not need to be positioned as the barrel (7) is mounted onto the body. In sum, said submachine gun contains a barrel front ejection (14) and barrel ramp (15) which allow the round to be pushed from the magazine (9) into the round chamber with the help of the mechanism (2) and also allow the mechanism (2) to lock onto the barrel (7).

In the invention, there is a fixed ejector (11) on the lower body (8) placed at the lower part of the mechanism (2). The function of the fixed ejector (11) is to eject the empty shell outside the submachine gun if the round is fired, or the live round if it is not fired. The cylindrical part of the said fixed ejector (11) is placed into the hole that is bored to its size on the lower body (8) and it is fixed to the body with the help of a pin (16). The fixed ejector (11) is not in contact with the rounds inside the magazine (9) or the mechanism (2) that moves within the upper body (1).

After the round is fired, the lug on the mechanism (2) that travels backward due to the explosion pulls the empty shell backward. The empty shell that travels backward along a straight line that is parallel to the axis of the barrel (7) changes direction when it hits the fixed ejector (11) and due in part to the lug that pulls it, and is ejected through the ejection window (12).

The length of the part of the fixed ejector (11) that hits the lower part of the empty shell can be changed to change the direction in which the empty shell will be ejected.

As a result, submachine guns of caliber 9×19 mm become lighter and more easily used with this invention.
